Mam do czynienia z problemami w usłudze REST usługi Jax-RS podczas próby aktualizacji obiektu zawierającego wyliczenia za pośrednictwem protokołu HTTP PUT.HTTP Put Enum przy użyciu usługi REST usługi JAX-RS
Umieszczam encję zakodowaną jako JSON, więc wyliczenia, których używam w tym JSON, są dostarczane jako łańcuchy.
otrzymuję następujący błąd:
Exception [EclipseLink-43] (Eclipse Persistence Services - 2.6.2.qualifier): org.eclipse.persistence.exceptions.DescriptorException
Exception Description: Missing class for indicator field value [AGENT] of type [class java.lang.String].

Pole Wartość czynnik jest wyliczenie w konta podmiotowego.
Dostaję tylko ten błąd w encji zawierających wyliczenia, w innych przypadkach HTTP PUT działa dobrze.
Zgaduję, że jako "AGENT" dostarczany jest jako ciąg znaków w JSON, nie można go przekształcić w wartość wyliczeniową.
Czy istnieje proste rozwiązanie problemu?
Dzięki za pomoc!
Edit jakiegoś więcej Kod:
Dobra, enum jest zdefiniowany następująco:
@XmlType(name = "type")
@XmlEnum
public enum AccountType implements TranslatableEnum {
@XmlEnumValue(value = "lov.account.type.customer")
CUSTOMER("lov.account.type.customer"),
@XmlEnumValue(value = "lov.account.type.agent")
AGENT("lov.account.type.agent")
//just getter/setter things following
}
HTTP PUT w REST-Service tak:
@PUT
@Path(value = "{id}")
@Consumes(value = MediaType.APPLICATION_JSON)
public void edit(@PathParam(value = "id") final String id, final T entity) {
getRepository().update(entity);
}
z update funkcja:
public T update(@Observes @Update T entity) {
getEntityManager().merge(entity);
return entity;
}
jakieś sugestie?
Czy wypróbowałeś następujące rozwiązanie: http://stackoverflow.com/a/12292355/1346996? – aribeiro
Dzięki za sugestię, próbowałem, ale błąd pozostaje ten sam. – EsSuch
Czy możesz dodać przychodzące json i klasę, do której ma zostać deserialized? – Ilya
